Abstract

The invention provides a liquid crystal display including a thin film transistor array panel according to an embodiment of the present invention includes: a substrate; a gate line formed on the substrate; a data line crossing the gate line; a thin film transistor connected to the gate and data lines; and a pixel electrode including first and second subpixel portions electrically connected to the thin film transistor, and a third subpixel portion capacitively coupled to at least one of the first and the second subpixel portions. Such an arrangement of a TFT permits a distribution of the tilt directions of liquid crystal molecules in the same pixel to improve lateral viewing of the liquid crystal display.
